I used to have this same problem, but not any more. I came up with the perfect method of cleaning the LCD panel. First of all, I had no idea that alcohol would damage the LCD. I normally use 90% Isopropyl Alcohol for cleaning everything on the smartphones and tablets that I repair. I might change that back to a pre-mixed 50% solution, but the 50% does not remove grease as well. I honestly don't think a 1-time cleaning using the 90% will cause a problem. I could believe that continued cleaning with the alcohol could cause damage, however. What works best for me is to follow this 3-step procedure. And take note, scrubbing an LCD with a back-and-forth motion will only get you frustrated, just as the previous poster had mentioned. I've been there, rubbing on an LCD for upwards of an hour, only ending with the same grease smudges that I started with. Well anyway, here's my 3-step process: 1. Using a micro fiber or dust-free cloth, or even a soft toilet paper, put a liberal amount of the alcohol on your cleaning...
I'd like to hear more about that too. Thus far, I have only found one person who has attempted something similar. A gentleman managed to chip away the glass digitizer from a 1st-generation iPhone, which also has the glass glued to the LCD panel. He said it took over 3 hours, but he managed to get it done by cracking and chipping away the glass piece by piece.
I cracked my iphone 4 glass, but the phone still works. One of the cracks ran right through my front-facing camera. About a month later, I decided to pick the shards off of the face where the camera is, and I was able to do so with ease. I'm wondering if I can pluck the rest of this glass off and replace it with a $30 glass display instead of blowing $150 on a new glass+LCD panel. If I do this, I will record it. I might be the first to pull this off and document it. For now, I have started a blog page to talk about the frequency of broken iPhone 4 glass displays. Check it out at http://carltonzone.com/blog/cracked-your-iphone-4-screen-you-might-want-to-read-this/ Update: When I broke my 3GS, you had to use a heat gun just to loosen the glue at the top and bottom of the digitizer screen. This was not easy at all, and was a frustrating process. You either don't heat it up enough, or you can over do it and warp the parts. I watched a video of a guy in Europe who took a first generation iPhone and a sharp...
